EARTH-AUGER.

SPECIFICATION forming part of Letters Patent No, 368,172, dated August 9, 1887.

Application filed September 27, 18%. Serial No. 214.641. (No model.)

To all whont it may concern.-

Be it known that I, JULIUS H. STowE, a citizen of the United States, residing at Martinsburg, in the county of Audrain and State of Missouri, have invented a certain new and useful Improvement in Earth-Angers, &c., of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure 1 is a perspective view of my improved auger, showing the shaft in place on the auger. Fig. 2 is a similar view showing the auger disconnected from the shaft and partly raised. Fig. 3 is a similar View of the auger enlarged, showing a modification of the means of permitting the shaft to remain in the 1101c during the withdrawal of the auger. Fig. 4 is a vertical section through the auger and showing part of the shaft in elevation, this figure showing another modification of the means for permitting the shaft tOTtilllEtll] in the hole during the withdrawal of the auger. Fig. 5 is an enlarged perspective view showing the upper end or neck of the auger and the lower end of the shaft, illustrating a form of connection between these parts. Fig. 6 is a side elevation of the neck on the upper end of the auger and the bell-mouth or funnel on the neck. Fig. 7 represents the flaring flange on the reamer shown in Figs. 1 and 2, which assists in permitting the auger to be elevated without striking the lower end of the shaft. Fig. 8 represents a flaring flange for the same purpose secured to the top of the groove in the auger shown in Fig. 3.

he principal object of my invention is to construct an anger in such a manner that the shaft may be disconnected therefrom and remain in the hole while the anger is being elevated to empty it. I have shown three different means of accomplishing this result, and many others could be conceived of without departing from the spirit of my invention.

Referring to the drawings, A represents an anger, on the upper end of which is secured, preferably by arms B, a hollow neck or sleeve, 0, which receives the lower end of the operating shaft or rod D, which is seen red thereto, preferably, by a bayonetjoint, E, which permits of a ready and convenient method of connecting the shaft to and disconnectingit from the anger, it only being necessary to lower the shaft into the neck, when the pin E on the shaft will enter the vertical part of the slots E of the joint, and then, by turning the shaft in the direction in which the anger is turned when in use, the parts will be connected together.

\Vhen the anger is full and has to be emptied, it is only necessary to turn the shaft backward slightly and then elevate it until its lower end is out of the neck O, and then the two are disconnected. To now .lift the auger to empty it without lifting the shaft also, it is necessary to provide some means to allow the auger to be raised while the shaft remains in the hole. To accomplish this 1 have shown in Figs. 1 and 2 a reamcr, F, secured to the auger, which cuts a hole larger than that made by the auger, so that when the shaft is disconnected from the auger and swung over against the edge of the hole, as shown in Fig. 2, the

auger may be removed without removing the shafting. Then, when the auger has been emptied and is lowered into the hole, the shaft is swung over to the center of the hole and lowered again into the neck of the anger, as already described, and to assist in directing the lower end of the shaft into the neck the latter may be provided with a funnel or bel1- mouth, G.

The form of the reamer F is shown in Fig. 7, its rear end having a web, H, with a projection, I, that fits upon the upper end of the auger, and its upper edge being flared inward at J, which constitutes a deflector, so that as the anger is raised the end of the shaft (should the shaft not be fitting close up against the wall of the hole) will be engaged by this flaring flange and forced outward against the side of the hole. The neck of the augcr is provided with a bail, L, to which a hoisting rope or cable, L, is connected tolift the anger. The lower end of the bail is secured to a cross-pin, M, on the neck. This pin and the openings in the ends of the bail receiving the pin are oval in shape, and the openings are somewhat larger than the pin, so that the bail is allowed to drop over into the position shown in dotted lines, Fig. 6, (when the auger has been lowered,) and will thus act to assist in lowering the shaft into the hollow neck of the auger, for the shaft will swing against this bail, and thus be prevented from moving farther in this direction, and by then dropping it it will enter the funnel or bell-mouth G. (See dotted lines, Fig. 6.)

As a modification of the reamer, I have shown the auger provided with a longitudinal depression or groove, N, (see Figs. 3 and 8,) in which the shaft fits as the anger is raised, this part of the auger being preferably provided with a flaring flange or deflector, N, at its upper end, which fills the function of the flange J in the other form.

In Fig. 4 I haveshown still another modification, or another means of permitting the auger to be raised without lifting the shaft, and in this case the anger is provided with a central sleeve or tube, 0, which slides over the shaft, and the bayonet-j oint E is located at the bottom of the auger. In this instance, when the shaft is turned backward to relieve the joint, the auger can he slipped up over the shaft and be removed from its upper end.

I haveshown and described my invention as applied to earth-angers, but it maybe used on drills and all kinds of boring apparatuses.

It will be apparent that with the use of my invention a great amount of labor in lifting and lowering the shafting is avoided.

I claim as my invention- 1. In combination with a shaft and an anger removable therefrom, a deflector at the top of the auger for preventing the shaft entering the auger when elevating the latter, as explained.

2. In combination with a shaft, a detachable auger having a longitudinal grooveor depression on the outside,'as and for the purpose set forth.

3. In combination with a shaft, a detacha- 40 ble auger having an outer longitudinal depression, and a deflector secured to the anger at the top of the depression, substantially as and for the purpose set forth.

4. Incombination with the auger having a depression, N, and provided with a hollow neck having a funnel or hell mouth, a shaft removably connected to the hollow neck,substantially as and for the purpose set forth.

5. In combination with the auger having a hollow neck and a depression, N, a shaft removably connected to the hollow neck, and a hinged bail secured to the neck with a limited lateral movement, substantially-as and for the purpose set forth.

6. In combination with an anger having a depression, N, and thevhollow neck, a shaft removably secured to the hollow neck, and a lifting-bail secured to the neck by an oval crosspin, substantially as and for the purpose set forth.
